3,095,173 MOVABLE MOUNT Anthony N. Paruolo, Norridge, 11]., assignor toAdvertising Metfl Display (30., Chicago, Hi, a corporation of IllinoisFiled June 20, 1961, Ser. No. 120,879 9 Claims. (Cl. 248-124) Thisinvention relates to a readily movable or portable mount, and moreparticularly relates to a readily movable mount for a window airconditioner. The mount is so constructed as to be manually pulled orpushed from room to room with a minimum of effort and is adjustable toconform with the sills of windows disposed at varying distances from thefioor level. This application is a continuation-in-part of my co-pendingapplication Serial No. 96,175, now abandoned, which was filed March 16,1961 and entitled Movable Mount.

Window air conditioners are normally adapted to cool certain limitedvolumes of air within a house. Usually a window air conditioner is ofsuch cooling capacity that it is able to cool the air within the room inwhich disposed to a desired temperature. Because of the limited coolingcapacity of window air conditioners, the cooling effect is not realizedin rooms located some distance from the conditioner.

Due to the weight and size of the normal window air conditioner, it isusually inserted by means of a permanent or semi-permanent installationin a window of a room in which cooling is particularly desired. Quiteoften air conditioners are permanently installed in the windows ofbedrooms whereby the temperatures within such room are maintainedcomfortably low during hot summer nights. However, during the day,little or no benefit from such a bedroom conditioner is obtained by ahousewife working in a distant kitchen or living room,

and consequently, the conditioner may be allowed to remain nonoperativeuntil night.

If, however, a window air conditioner could be readily moved into andinstalled with ease in a minimum amount of time in any desired room ofthe house in which cooling effects are desired, a single conditionercould etficiently cool a room, such as a living room, during the daytime and be moved to a bedroom to cool the latter room during the night.

It is an object of this invention, therefore, to provide a novel,movable mount particularly adapted to assist in readily moving a windowair conditioner to a desired window location in a house or ofiice,adjacent which cooling effects are desired.

It is another object of this invention to provide a movable mount for awindow air conditioner which is adapted to readily position a supportedair conditioner in proper disposition relative to a variety of windowopenings normally found in a home or other building structure.

It is a further object of this invention to provide a readily movablemount for an air conditioner which is so constructed as to assure readymovement of an air conditioner disposed thereon over plane surfaces withsubstantially no danger of tipping the mount or the air conditionermounted thereon.

It is still another object of this invention to provide a readilymovable mount for an air conditioner which is simple and lightweight instructure, and although adjustable, of sturdy construction so as to moveand support in safety window air conditioners of substantial size andweight.

It is yet another object of this invention to provide a novel mount foran air conditioner or the like, which not only facilitates movementthereof, but which also functions as an integral part of theinstallation, dispens- 3,095,173 Patented June 25, 1963 I ing withadditional supporting structure cost and installation.

It is another object of this invention to provide a mount constructionemploying novel locking sleeves which prevent extensible frame portionsfrom moving or vibrating relative to supporting frame port-ions, therebyassuring a sturdy assembly in all positions of use.

It is a further object of this invention to provide a movable mount foran air conditioner or the like employing novel floating anchor meanswhich assure secure enga-gcment of the air conditioner to the mount, aswill hereinafter be explained in greater detail.

The above and other objects of this invention will become more apparentfrom the following detailed description when read in the light of theaccompanying drawings and appended claims.

In one embodiment of this invention, a readily movable mount,particularly adapted for use with a window air conditioner, is provided.Such mount comprises a first lower frame portion having spaced, verticaltubular members in which a spaced pair of rods or tubular members of anupper frame portion which are of L-shaped configuration and lesserdiametr-ic dimensions are telescopically received. Superposed transversechannel members, one of which is connected to lower frame portionsengaging the vertical tubular members of the lower frame member and theother of which is connected to upper portions of the smaller-diameterL-shaped members, assist in maintaining the telescopically engagingelements of each pair in fixed spaced relationship.

Opposed parallel guide means are secured to terminal horizontal portionsof said L-shaped frame members and supportingly engage opposed carriagemeans, reciprocally movable in the horizontal plane, on which an airconditioner may be mounted. A rotatable threaded rod member threadedlyengaging a tapped opening of the lower transverse channel and pinned atits upper end limit to the upper transverse channel comprises aregulating means whereby the position of the upper frame portion may beregulated relative to the underlying frame portion.

In the normal course of use, the mount which is readily manually pulledor pushed with the assistance of casters mounted on the lower frameportion thereof is moved adjacent a window from which an air conditionerdisposed on the mount is to project. The vertical position of the airconditioner is regulated by the threaded rod after which the conditionermay move into the window opening by means of the horizontally movablecarriage members, as will hereinafter be explained in greater detail.

In a modified mount construction the telescopic engagement between theupper and lower frame portions is rendered vibration free by means ofthreaded locking sleeves. The sleeves threadedly engage upper endportions of the larger telescopically engaging tubular portions of theframe and concomitantly urge a split ring into the tube interval.

The modified mount also employs a carriage construction employing afloating anchoring nut which assures proper engagement with thesupported air conditioner. The various features of the modifiedconstruction may be employed singly with the mount construction firsthereinafter described.

For a more complete understanding of this invention, reference will nowbe made to the drawings wherein:

Mount Frame Referring now more particularly to FIG. 1, a mount 10,particularly adapted to support a window air conditioner and assist inreadily moving the same over substantially level surfaces isillustrated. The mount is seen to comprise a lowermost tubular frameelement 12, which is substantially rectangular in configuration, onwhich four casters 14 are mounted at corner portions thereof. Thecasters are freely pivotal about their pintles and, accordingly, mount10 may be readily pushed or pulled in any direction on a plane surface.

Supported in substantially vertical planes on opposed portions of thelowermost tubular frame element 12 are opposed parallel, vertical framemembers 16 which may be bolted or otherwise suitably affixed to theunderlying frame element 12. One vertically disposed tubular arm 16a ofeach frame element 16 telescopically receives a lower leg portion 18L ofan L-shaped rod or tubular member 18 in the manner most clearly seen inFIGS. 1 and 3. Upper portions of frame elements 16 are maintained inspaced relationship by means of transverse bar 20 which may be securedat opposed end limits to frame elements 16 by screws 22 or otherequivalent securing means.

Mount Guides Secured to distal horizontal leg portions 18a of theL-shaped members 18 are opposed guides 24. The guides 24 may be securedto distal arm portions 18a of'each member 18 by means of nut and boltassemblies 26, most clearly seen in FIG. 5, or other equivalent securingmeans.

A transverse channel member 28, most clearly seen in FIGS. 1 and 6,maintains opposed distal portions 18a of members 18 in parallel, spacedrelationship, and as willbe noted from FIG. 5, may be secured toportions 18a of L-shaped members 18 by nut and bolt assemblies 26 whichalso secure guides 24 to distal legs 18a. Thus, L-shaped members 18,transverse channel 28 and the opposed parallel guides 24 will move as aunit relative to the underlying legs 16a of frame elements 16 in whichlower vertical portions 18L of the L-shaped members 18 aretelescopically received.

Frame Regulating Means It will be noted from FIG. 6 that the transversebar 20 and transverse channel 28 are in superposed relationship in thevertical plane and, accordingly, enable threaded rod 30, most clearlyseen in FIGS. 1, 3 and 4,-to serve 4- as a connecting means forregulating the interval between the upper portions of mount 10 and thelower frame portions of such mount. Because of the telescopic engagementbetween leg portions 18L and tubular members 16a, it is apparent thatthe upper portions of the mount 10 are extensible relative to the lowerframe portions of the mount. The threaded rod 30 has handle 32 securedto the lower terminal end limit thereof. Threaded rod 30 also threadedlyengages tapped nut 34 fixedly mounted on lower transverse member 20.Since the upper terminal limit of rod 30 is rotatable relative totransverse channel 28 but does not axially move relative thereto,rotatable movement of rod 38 will raise or lower channel 28 (dependingupon the direction of rotation) and the other mount elements movabletherewith relative to transverse bar 20 and the lower frame elements ofthe mount.

M onnt Carriage Members As will be more clearly seen from FIG. 5, guides24 have a substantially C-shaped cross sectional configuration and arearranged in face-to-face relationship. It is the purpose of guides 24 tosupportingly receive opposed carriage members 36 and gmide the same inthe course of limited reciprocal movement in the horizontal plane.Opposed carriage members 36 are maintained in parallel spacedrelationship by means of interconnecting tubular handle member or rod38, more clearly seen in FIGS. 1 and 6. End portions of rod 38 aresecured to opposed carriage members 36 by means of screws 40 (seeFIG. 1) or other equivalent means.

Each of the opposed guides 24 has a substantially horizontally disposedsupporting surface portion 42 over which wheel members 44 journalled inopposed end portions of each carriage member 36 may rotatably move. Inaddition, to facilitate movement of each carriage member 36 over supportsurface 42 of each guide 24, a hard plastic projection 46 mounted inportion 42 of guide 24 may be employed to maintain the level dispositionof surface portion 37 of each carriage member 36 and in addition reducefriction in the course of movement of each carriage member relative tothe supporting guide.

It will also be seen from FIG. 5 that longitudinal edge portion 48 ofeach guide, which is hook-like in cross sectional configuration, definesan elongate recess 50. Upper off-set longitudinal edge portion 52 ofeach carriage member 36 having spaced rollers 54, one of Which isclearly seen in FIG. 5, mounted thereon, reciprocally moves in [recess50 and is guided by edge portion 48 in the course of carriage memberreciprocal movement, as is apparent from FIGS. 4 and 5. Hook portion 48of each guide prevents undue lateral movement of the opposed carriagemembers 36 and interconnecting tubular member 38.

It is seen in FIG. 5 that normally, carriage members will readily moveover supporting surfaces 42 of guides 24 with the assistance of wheels44 and projections 46 tending to reduce friction between the relativelymoving members. However, in the course of a pushing movement of theopposed carriage members 36 relative to guides 24, an upward thrust maybe given to the carriage members as a result of which, rollers 54 willreadily engage inner surface portions of longitudinalportion 48 of theguides 24 and thereby facilitate relative movement between the guide andthe carriage portions.

Limits of Carriage Movement One end limit of reciprocal movement o-f-thecarriage assembly, comprising opposed carriage members 36 andinterconnecting member 38, and the guides 24 isdefined by raised flanges56, more clearly seen in FIG. 1, defining one longitudinal end limit ofthe lower surface portion 42 of each guide 24. The longitudinalmovementof the assembly relative to guides 24 in the opposite directionis defined by engagement between terminal ends 58 of carriage rod 38 anda distal longitudinal edge 60, more clearly seen in FIGS. 1 and 6, ofthe transverse channel 28.

Locking Levers In the normal course of use, an air conditioner isinitially mounted upon opposed carriage members 36 of mount by means ofscrews which threadedly engage tapped apertures disposed in opposed sideportions of an air conditioner, such as the air conditioner 64illustrated in FIG. 2. The securing screws have enlarged heads and shankportions which traverse apertures 66, which do not permit passage of thescrew heads. Apertures 66 are predeterminately spaced to conform withthe air conditioner tapped apertures and formed in each carriage member36. Enlarged apertures 68 in the vertical wall portions of guides 24,more clearly seen in FIG. 1, facilitate the initial securing of the airconditioner to the opposed carriage members 36.

In the course of the initial securing of the air conditioner to themount, the reciprocally movable carriage assembly must have carriageelements 36 thereof in substantially co-extensive relationship with thesupporting guides 24 in the manner illustrated in FIG. 1. In suchrelative disposition apertures 66 of carriage members 36 will beconcentric with apertures 68 of guides 24.

To facilitate the attaining of this desired co-extensive relationshipbetween the carriage members and the guide members, pivoting lockingelements 7 0, one of which is more clearly seen in the fragmentary viewof FIG. 7, are employed. Locking elements 70 comprise metal strips whichare pivotally mounted in an oif-center condition, whereby one endportion always has a tendency to pivot up and away from the bar member38. The longer heavier portion extending from the pivot point has thenatural tendency to pivot downwardly. The end limit of the pivotalmovement of each element 70 is defined by one edge 71 of recess 73disposed in the carriage member on which mounted, as is more clearlyseen in FIG. 7.

It will be noted from FIG. 1 that in the co-extensive relationshipdepicted between the guides and carriage members, the upwardly pivotingterminal end portion of each locking lever 70 will pivot upwardly,partially projectin-g through opening 72 formed in each longitudinalportion 48 of each guide member 24. It will also be seen from FIG. 1that in the co-extensive relationship between the guides and carriagemembers illustrated, movement of the carriage members in one directionis prevented by the raised flange portions 56 which function as stops.The lever members 70 prevent longitudinal movement of the carriagemembers on which the air conditioner is mounted in the oppositedirection by striking edge portion 74 of each recess 72. Edge portions74 comprise a portion of guides 24 and define one end limit of eachopening 72.

Mount Use After an air conditioner, such as conditioner 64, has beensecured to the opposed carriage members 36 by means of screws passingthrough aperture 66 of each carriage member, the mount and airconditioner may be readily moved into a desired window opening forpurposes of cooling a volume of air adjacent the window in which theconditioner is disposed. Prior to mounting of the conditioner on themount 10 and prior to movement of the mount, the upper extensiblecarriage assembly and supporting L-shaped members 18 are preferablyretracted into the lowermost position by means of threaded rod 30 inorder that the center of gravity of the air conditioner and mountassembly may be as low as possible, thereby maintaining danger oftipping such assembly at a minimum.

Upon arrival at a window opening, such as the opening of window 76 ofFIG. 2, the following steps take place. The air conditioner 64 is raiseduntil the conditioner and supporting carriage members are approximatelyone-half inch above the sill of the window from which the airconditioner will project. Following this vertical movement of the airconditioner and attached carriage assembly, upper portions of theopposed locking levers 70 are depressed and simultaneously, with thelevers in the lower non-locking position, the conditioner and attachedcarriage assembly are horizontally moved into the window opening.

To-assist in this movement, one foot of the person installing the airconditioner may engage ribbed member 77 composed of rubber or othernon-skid material disposed on the leg of the lower frame portion 12disposed beneath carriage bar 38. As previously mentioned, engagement ofthe terminal end limits 58 of carriage assembly bar 38 and distallongitudinal edge 60 of transverse channel 28 will prevent the airconditioner and carriage assembly from moving beyond a certain maximumdistance into the window opening.

After the air conditioner is properly disposed relative to the windowsash, the air conditioner is lowered by means of handle 32 and rod 30 sothat distal terminal portions of the opposed carriage members 36 whichnow project beyond distal end limits of guides 24, in the mannerillustrated in FIG. 6, rest on the window sill. The window sash is thenlowered and any expandable adapter members inserted in place so that noexposed area exists between the periphery of the air conditioner andlateral portions of the opening normally defined by the window.

The end portion of the air conditioner projecting from the windowopening is now locked between the lowered 'WlIlClOW sash and theunderlying window sill. In such condition the adjusting handle 32 forthreaded rod 30 may again be employed for purposes of raising the airconditioner and carriage assembly until the portion of the airconditioner projecting into the window opening possesses a slightlydownward tilt. Such tilting is desired to assure proper drainage of anymoisture which may be removed by the air conditioner from theconditioner so that such moisture will be discharged outside the room.Since the movement of the carriage members and conditioner relative tothe guide portions 24 of the provided mount have moved the center ofgravity of the conditioner toward the window opening, the last-mentionedupward movement of the threaded rod will in effect provide a tiltingaction of the conditioner, at which time carriage rollers 54 may comeinto play.

It will be most apparent from FIGS. 4 and 5, the latter figuredisclosing securing of the upper terminal end limit of threaded rod 30to transverse channel 28 by means of cotter pin and washer assembly 80,that the threaded rod 30 is not centrally disposed relative to the twotransverse members 20 and 28. Inasmuch as the center of gravity of airconditioners is not in a central position, the point of engagement ofthreaded rod 30 with transverse channel 28 and the disposition ofchannel 28 relative to L- shaped arms 18 are predeterminately selectedto assure the application of force to the channel by the threaded rod atapproximately the center of gravity of the conditioner. As a result ofsuch arrangement, any lifting force applied to the conditioner will bemost effectively utilized when the carriage assembly is in the positionseen in FIG. 1.

Modified Mount Construction FIGS. 8 through 12 of the drawing relate toa modified movable mount construction. It will be apparent from theselatter figures that portions of the modified movable mount 90, which arethe same 'as those in the movable mount 10 of FIGS. 1 through 7, bearthe same reference numerals.

Modified Frame Construction It Will be noted from FIG. 8 that althoughthe illus trated movable mount possesses a lowermost tubular frameelement 12 and casters which are substantially the same as components 12and 14 illustrated in FIG. 1, the

frame components attached to the tubular element 12 of the mount 96differ from those illustrated in FIG. 1.

Secured to the lowermost tubular frame element 12 in FIG. 8 are opposedsubstantially vertically disposed tubular members 92 which are welded toelement 12 at 94. Tubular elements 96 reinforce the connection betweenvertical elements 92 and frame element 12 by being welded to elements 92at 98 and to element 12 at 190.

It will be appreciated from a comparison of FIGS. 1 and 8 that since thevertical tubular members 92 of mount 91} are vertical throughout theirentire length, lower vertical portions 18L of the frame members 18 maybe longer in FIG. 8 than in FIG. 1 because of the absence of any curvedportion of the telescopically receiving frame portion of the mount. Byemploying a lowermost frame construction, such as illustrated in FIG. 8,portions 18L of the uppermost frame may be longer, providing greaterstability in the mount 96 than is obtained in the mount 10 of FIG. 1.

Inasmuch as the lowermost frame components of the mount 90 are composedof a few parts which are welded together, the cost of such assembly isless than that of the lowermost frame components of FIG. 1. As will beseen from FIG. 8, tubular members 96 of the lowermost frame constructionmay be of a smaller outside diameter than the telescopically receivingtubular members 92, thereby further assisting in lessening the cost ofthis construction over that illustrated in FIG. 1.

Locking Sleeves As above pointed out, the telescopic engagement betweenvertical members 18L of the upper frame portion of mount 99 and verticaltubular portions 92 of the latter mount is substantially the same as thetelescopic engagement between the frame components 18L and 16a ofFIG. 1. Mount 90, however,is distinguished from the movable mount 10 ofFIG. 1 by being provided with a frame locking means to assure a fixedrelationship between telescoping members of the upper and lower frameportions.

As is seen in FIG. 8, the upper frame assembly of the mount 90'possesses the transverse channel 28, transverse member 20, nut 24 andthreaded rod 30, which are employed in the mount 10 of FIG. 1. However,because of manufacturing tolerances, slight play is always presentbetween the vertical frame portions 18L and the lower frame portions 16aof the movable mount 10. The movable mount 94) of FIG. 8 eliminates anyplay between the telescoping frame components by employing lockingsleeves 102 and'split rings 104, illustrated in FIG. 11.

In the normal course of use of the movable mount 90, the upper frameportion and attached conditioner can be moved into the desired verticalposition and inserted in a window opening in the manner previouslydescribed in connection with movable mount 10. Once the conditioner isin place, locking sleeves 102, having the internal threads 106,threadedly engage the external threads 108 disposed on the upper endportion of each vertical tube component 92 of the lowermost frameportion of the illustrated movable mount 90.

In the course'of threadedly engaging the upper portion of the verticalframe tubular members 92, split rings 104 are urged into the intervalbetween vertical tubular portions 18L of the upper frame and verticaltubular members 92 of the lower frame portions of the movable mount 90.Locking sleeves 102, in conjunction with the split rings 104, assist inproviding a rigid frame assembly which is substantially free of play andnot subject to vibration. The sleeves 102 also assure disposition of theupper frame portion of the illustrated mount in a desired horizontalplane, regardless of the weight of the air conditioner which may besupported thereby.

8 Modified Carriage Construction I It will be noted from FIG. 9 thatalthough the opposed guides 24 are precisely the same as the glidesillustrated in FIGS. 1 through 7 of the drawings, carriage members 110employed with the movable mount are somewhat different from the carriagemembers 36 of the movablemount 10 previously described.

It is apparent from FIG. 9 that no roller members, are employed inconjunction with carriage members 110. Instead, the means for reducingfriction between the reciprocally movable carriage members and thesupporting guides 24 comprise supporting plastic projections 46 and 112which are mounted in the lower supporting surface portion 42 of theguides 24-. Plastic member 46, illustrated in FIG. 9, is precisely thesame as that illustrated in FIG. 5. The plastic members 112, which aremounted in opposed end portions of surface portion 42 of each guide 24,dispense with the need for rollers 44, illustrated in FIG. 5. 9

Although the opposed carriage members 110 of the mount 90 are maintainedin spaced relationship by the same tubular handle 38, which is employedwith the mount fers somewhat from that of the carriage members 36previously described. It will be noted from FIG. 9 that an upper offsetlongitudinal edge portion 114 of carriage member 110 is not offset tothe same degree as edge portion 52 of carriage member 36. Consequently,pivotal locking levers 116 do not traverse an opening formed in thecarriage member 110, but are mounted on pins 118, most clearly seen inFIGS. 9' and 10, which project from the innermost surface of each offsetlongitudinal edge portion 114 of the carriage members 110. The pivotallocking levers 116 are mounted in an off-center condition whereby thelonger heavier portion of the lever is disposed toward the mount handle38', as is most apparent from FIG. 10. The end limit of this downwardpivotal movement is defined by an angularly disposed stop member 129,which is welded or otherwise suitably secured to a surface portion ofeach carriage member 110 in the manner most clearly seen in FIG. 9. Whenthe locking levers 116 engage stop members 120 upper stop edge portions122 are in a position to engage edge portion 74 of recess 72 formed ineach guide member 24, in the manner illustrated in FIG. 10. 1

Relative positioning between carriage members 110 and the supportingguides 24- of the movable mount 90 is assisted by means of the plasticmembers 112 mounted in the lower surface portion 42 of each guide.Plastic members 126 mounted on the surface portion of the longitudinaledge portion of 114 of each carriage member 110 disposed toward theterminal distal end of each hook-like portion 48 of the guides 44 alsoassist in maintaining desired carriage-guide relationship. In order toprovide proper spaced relationship between the bottom portion of eachcarriage member 110 and the vertical wall portions of each guide 24, anelongate channel portion 110A is welded or otherwise suitably aflixedalong the lower longitudinal edge of each carriage member 110 in themanner illustrated most clearly in FIG. 9.

Carriage Members Adjustable Anchors 128 are formed in the vertical wallportions of each carriage member 110. Movably positionably in eachenlarged aperture is a pivotally mounted anchor or nut member 130, mostclearly seen in FIGS. 10 and 12. Since the nut members 130 are pivotallymovable within the carriage aperture 128, a screw member may engage anair conditioner tapped aperture (which is formed in the course ofconditioner manufacture) with relative ease in the course of securingsuch conditioner to the carriage members. The floating anchors 130eliminate completely any problem of aperture misalignment which may beoccasioned by manufacturing tolerances and encountered in the course ofsecuring an air conditioner to the opposed carriage members of themovable mount 90.

It is seen from the foregoing disclosure that the modified mountconstruction illustrated in FIGS. 8 through 12, various changes may bemade in the basic mount construction provided by this invention whichwill facilitate attachment to the mount of an air conditioner, as wellas positioning of the air conditioner in a window opening.

It is apparent, therefore, that a novel mount has been provided for aroom air conditioner which enables the same to be readily moved fromwindow to window within a house or other enclosure so that selectedportions of a home or ofiice may be cooled as desired. Thus, aconditioner may be readily moved by means of the abovedescribed mount tothe window of a kitchen in day time so that cooling effects may beimparted to that portion of the home most frequently used by theinhabitants during the day time, and at night the conditioner may bereadily moved by means of the mount 10 to a bedroom window so thatcooling effects may be imparted to the bedroom during the night.

A window air conditioner which had heretofore required permanent orsemi-perrnanent installation may now serve a number of rooms, asdesired, during the day because of the rapidity and facility with whichthe conditioner may be moved to any desired window.

The foregoing description has illustrated the ease with which theconditioner may be adjusted to be properly disposed witlun windowopenings of various heights. The novel mount structures above describedalso clearly demonstrate that the air conditioner may be moved insubstantially complete safety without danger of tipping.

It is apparent from the foregoing that a number of changes may be madein the mount structures which will provide a resulting constructionwhich does not depart from the scope of hte invention described. It iintended, therefore, that this invention be limited only by the scope ofthe appended claims.
